Hengest

Hengest of Kent (425-500) was the founder of the Kingdom of Kent, reigning from 455 to 500, preceding Oisc of Kent.

Biography
Hengest was the brother of Horsa and was a Germanic mercenary. Vortigern, king of the Romano-British, brought the brothers to Roman Britain as generals to lead his armies, and Hengest fought against Scotland's Celts for Vortigern. However, Hengest and Horsa revolted, killing Vortigern's son and adding the Kingdom of Sussex and the Kingdom of Essex to their own kingdoms. Hengest founded the Kingdom of Kent in 455, and was its ruler until his death in 500. Oisc of Kent succeeded him as King of Kent upon his death.
